The so-called "normal force" is usually a force exerted by a surface that is supporting an object. For a body in orbit there is no support surface or normal force.LeahLala said:What happens to the normal reaction of the force of gravity on a body orbiting around the Earth?
The gravitational force between two bodies is responsible for the motion of those bodies towards each other. The larger the mass of the bodies, the greater the gravitational force, and the faster the bodies will accelerate towards each other.
No, the gravitational force is always positive. It is a force of attraction between two bodies and can never be repulsive.
The gravitational force is inversely proportional to the square of the distance between two bodies. This means that as the distance between two bodies increases, the gravitational force between them decreases.
The gravitational force acting on a body is directly proportional to its mass. This means that the larger the mass of a body, the greater the gravitational force acting on it.
No, the gravitational force depends on the mass and distance of the objects involved. Objects with larger masses will experience a greater gravitational force, and objects that are closer together will experience a stronger gravitational force.
